P R PART 2 E S E N T P O S I T I O N Waste Management Plan 2005 – 2010 Part 2 - Present Position 4 WASTE GENERATION 4.1 DUBLIN REGIONAL WASTE QUANTITIES Since the adoption of the previous Waste Management Plan (1998) waste arisings have continued to grow in the Region reflecting the national trend. Since then the reporting and recording mechanisms for waste data have improved significantly for household, commercial and construction & demolition waste streams. Nevertheless there is significant room for improvement in waste reporting, particularly for the private waste management sector. The waste quantities presented in this Plan are for the year 2003 and were obtained from numerous sources that are referenced throughout this document. The key sources include: x Local Authority (EPA) National Waste Database Returns 2003; x Waste Licensed Facilities – Annual Environmental Reports (AERs) 2003; x Waste Collection Permits – AERs 2003; x EPA National Hazardous Waste Management Plan 2001; The format for the presentation of waste quantities is set out in the Waste Management (Planning) Regulations, 1997. Table 4.1 outlines the key waste categories, and corresponding waste arisings reported to each Local Authority in Dublin Region for the year ended 2003.

This is 20% higher than in 1997. The increase is due to the growth in the number of households, and a growth of 1.6% per annum in the amount of waste each household is generating. Table 4.2 details household waste growth since 1997, and Table 4.3 presents a breakdown of household waste by category. (A further breakdown of household waste generation is provided in Table 7.1).

In 2003, 480,682 tonnes of commercial waste was generated in the Region, this is 56% (171,036 tonnes) more than what was quoted in the last Plan (1997 data). This figure needs to be viewed with caution however, as it is likely that a large volume of industrial waste is being reported as ‘commercial’. In addition improved reporting by private waste collectors through the waste collection permitting system has lead to the marked increase in the quantity of commercial waste being reported. In Table 4.4 below we have included estimated data for the waste collected in both Commercial and Industrial sectors, although the split between C&I is estimated in some cases. In general, there is a poor differentiation between waste defined as Commercial (generated by commercial enterprises such as shops, offices, administration etc.) and Industrial (generated by industry). Much of the non-process waste generated by industries is similar to that generated in commerce, and is collected by private or ‘commercial’ waste companies. Such waste includes packaging, office waste, canteen waste etc. and hence is dealt with at the same facilities as municipal waste.

This figure is primarily the industrial waste that enters the ‘municipal’ waste collection system and which is reported through the collection permits and permitted facility Annual Environmental Reports (AERs). In 1997, an estimated 408,156 tonnes of industrial waste was generated, this figure was estimated from employee numbers, so cannot be directly compared with the 2003 figure. In future it is recommended that the actual quantities of commercial/ industrial waste reported by waste management companies be used as the basis for waste planning, as reported in Table 4.4 above. 4.1.4 Construction and Demolition (C&D) Waste The primary source of data regarding the generation of C&D waste is from the records of licensed facilities and permitted sites (incl. data from counties Kildare, Meath and Wicklow). The best estimate of C&D waste arisings for the Region in 2003 is 3.96 million tonnes. A major difference in the management of this waste stream is the treatment of C&D waste in landfills. In 1997 1,223,013 tonnes were disposed of in landfills, in 2003 715,000 tonnes was sent to landfill, however the vast majority of this material was reported as being used in landfill engineering or site restoration works. One other factor in the large increase in the estimate of C&D waste has been the volumes of material sent to sites under Waste Permit. Records indicate that large volumes of material are being deposited in Counties Kildare, Wicklow and Meath, as well as in Fingal and to a lesser extent in South Dublin and Dun Laoghaire-Rathdown. More details are provided in Section 10.

This is based on the employee numbers, using a per capita waste generation factor for the sector. 4.1.7 Sludges (Municipal/Industrial) The Waste Management (Planning) Regulations, 1997 require that the Plan specify to the extent possible the quantities of waste arising within the relevant functional area, classified under categories in Table 4.6. ) Operational Sludge Management Plans have been prepared for both DLRCC and FCC. SDCC has not prepared a plan as no waste water/water treatment sludge is generated within the county and the water treatment sludge from the Leixlip Plant is incorporated into the FCC Plan. Dublin City Council’s sludge planning arrangements have been set out in the planning and environmental impact assessment of the Ringsend facility, which includes details on the policy for treatment and disposal of sludge. Approximately 17,954 tonnes (dry-solids) of non-hazardous sludge (municipal and industrial sludge) are generated within the Region per annum according to the aforementioned reports, details of which are outlined in Table 4.6.
